The apparatus used for measuring an LDR's resistance involves a circuit setup with the LDR and a fixed resistor in series, powered by a constant voltage source.
How to get how the apparatus is used to measure the resistance of the LDR
Current passing through the LDR is measured by an ammeter, while a voltmeter measures the voltage across it. Maintaining consistent light intensity, data on current and voltage are recorded.
Using Ohm's Law (R = V/I), where R is resistance, V is voltage, and I is current, the LDR's resistance can be calculated.
This setup allows observation of how the LDR's resistance changes with varying light conditions, providing insights into its behavior. Caution is essential when handling electrical circuits for safety purposes.
